Re: FNG on board
The key comment in your question is "I love horsepower". With that in mind you want the SRT6. If you just want a fun car to drive in the twisties, it doesn't really matter much, however if you want "kick in the pants" power, no question, you want the
SRT6.
One caveat, the SRT6 only comes with an autostick. If you are looking for a manual, you have to go Limited. The SRT6 transmission is one of the finest autos I have ever driven, great for driving in rush hour and flexible enough to hold a gear on the track.
Good luck.
